Dear Brahmen,
Ian requested instructions on how to use the Zdc
Z vertex. Please test the examples below.
Yours Michael
Hi Ian,
to use the calibrated vertex data from ZDC you need to add BrZdcRdoModule
to your bratmain script:
... your bratmain script
BrAppendContainer *appModule= new BrAppendContainer ("Append", "IO helper");
mainModule->AddModule (appModule);
//----- ZDC RDO module
zdcRdoModule= new BrZdcRdoModule ("ZDC", "zero-degree");
zdcRdoModule->SetUseSlewing (kTRUE);
zdcRdoModule->SetUseOffset (kTRUE);
appModule->AddModule (zdcRdoModule);
then in your main (where you do need the z-vertex from ZDC) analysis class
you need to add in Event() method these few lines:
#if !defined BRAT_BrZdcRdo
#include "BrZdcRdo.h"
#endif
...
void BrYourAnalysisModule::Event (BrEventNode *inNode, BrEventNode *outNode)
{
SetState(kEvent);
...
//----- get ZDC vertex
BrZdcRdo *rdoZDC= (BrZdcRdo*) inNode->GetObject ("RdoZDC");
if (!rdoZDC) return;
Float_t z= rdoZDC->GetZ (); // this is a calibrated vertex from the ZDC
}
you can look at the files in /brat/scripts/calib/zdc/ZdcVtxOffset.C as an
example of script, and at /brat/modules/calib/vertex/BrZdcVertexCalModule.cxx
as an example of "analysis" class which uses z-vertex from ZDC. All these are
in BRAT. If you have troubles, please write me!
Andrei.
